Specification of Letters Patent.

Patented Jan. 12, 1915.

Application filed April 21, 1914. Serial N 0. 833,503.

To all whom it may concern:

Be it known that I, ELIAS GRAHAM, a citizen of the United States, residing at Hazel Dell, in the county of Cumberland and State of Illinois, have invented certain new and useful Improvements in Sanitary Drinking-Fountains; and I do hereby de clare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to new and useful. improvements in sanitary drinking fountains and comprises essentially means whereby, when pressure is applied to a piston mounted in a cylinder within the well, water may be caused to be dispensed at the drinking cup, means being provided for drainage of the water and for the adjustment of the various parts.

The invention comprises specifically a water containing tank having a valved pis ton therein, the stem of which is adapted to be depressed by pressure and returned to its normal position by means of a float.

The invention comprises various details of construction, combinations and arrangements of parts which will be hereinafter fully described, shown in the accompanying drawings and then specifically defined in the appended claims.

I illustrate my invention in the accompanying drawings, in which:

Figure 1 is a vertical central sectional view through the apparatus. Fig. 2 is'a sectional view showing the drain valve open. Fig. 3 is a similar view showing the drain valve closed. Fig. 4.- is a sectional View through the valve casing showing the drain valve open. Fig. 5 is a sectional view showing the valve regulating the flow of water to the pen stock, and Fig. 6 is a sectional view showing the valve illustrated in Fig. 5 closing the passageway to the pen stock.

Reference now being had to the details of the drawings by letter, A designates a well in which is positioned a cylinder B, open at its top, and from the lower portion of which a pipe C leads and extends up through the platform D and has threaded connection at D with a goose neck pipe D communicating with a valve casing D hav-. ing a spring-pressed valve D therein, and D designates a pipe having a handle D upon which a pail may be hung when it is desired to dispense water from the pipe D D designates a T-union connected to the pipe D which in turn is connected to an elbow-D the latter being attached to a pipe D upon which the drinking cup D is mounted. A drainage valve E has a shaft journaled in apertures in said T-connection and a spring F bears against said valve and normally holds the same open. A hand wheel II is fastened to one end of the shaft carrying the valve and affords means whereby the valve may be held closed under the tension of said spring while the fountain is being used and, when pressure is released from the hand wheel, the valve will normally return to its open position, allowing any water which might remain in the cup or the pipes connected thereto to drain through the exit pipe I which leads through the plat-' form and through the wall of the well.

A piston head F is made to fit within the cylinder B within the well and is provided with a stem Q, and O designates a hemispherical ball valve and O is a cage fastened to the piston head and retains the valve in position and allows the valve to freely seat and unseat. Fastened to the upper end of the piston stem is a platform Q, provided with apertures for the reception of the guide rods R which at their lower ends, are fastened to the float S, suitable set screws T being fastened in the shells T through which the rods pass and adapted to hold the latter in adjusted positions.

The operation of my invention will be readily understood and is as follows: The parts are shown in the drawings in their normal positions. When it is desired to cause water to be forced up through to the drinking cup, the operator, by depressing the platform Q, may cause the piston to be forced down within the cylinder B, the valves closing the apertures in said piston and forcing the water beneath the piston of the valves in the piston as the latter moves upward.

When the operator releases the hand wheel which regulates the valve, the latter will be thrown to an open position by the influence of the spring which engages the same, thus draining the cup and pipes which have immediate pipe'connections therewith. In the event of it being desired to draw water from the pipe D it may be done by turning the spring-pressed valve D to its limit in one direction which will out off the water from passing to the drinking fount and allow the same to make exit through the pipe D What I claim to be new is:

l. A drinking fountain comprising, in combination with a well,a tank therein, a pipe leading from the latter, a drinking cup connected to said pipe and a drainage pipe leading from the latter, a valve in said drainag pipe, a piston within said tank, a stem secured to the piston, a float fastened to the piston and mounted within the well and serving to normally return the piston after having been depressed to discharge water from the cylinder, as set forth.

2. A drinking fountain comprising, in

combination with a well, a tank therein, a pipe leading from the latter, a drinking cup connected to said pipe and a drainage pipe leading from the latter, a valve in said drainage pipe, a piston within said tank, a stem secured to the piston, a crosspiece at the upper end of said stem with apertures therein, a float mounted within the well, rods connected to said float and passing through said apertures, and means for holding the rods in adjusted positions, as set forth.

3. A drinking fountain comprising, in combination with a well, a tank therein, a pipe leading from the latter, a pipe having threaded connection with the pipe which leads from the tank, a drinking cup and pipe connection between the same and said siphon-shaped pipe, said connections being detachable, a drainage pipe in the cup, and a spring-pressed valve in said drainage pipe, as set forth.

In testimony whereof I hereunto afiix my signature in presenceof two witnesses.
